SASA FLANGE material center
Industrial piping materials, organized for procurement.
Compare stainless, duplex, nickel, alloy and carbon steels, titanium, copper nickel, 17-4 PH, and AL-6XN—then connect each material decision to existing flange, fitting, and valve routes.
Material families
One useful page per material family.
Each page contains grade comparison, existing product routes, tiêu chuẩn, RFQ controls, and direct technical answers—without multiplying thin taxonomy archives.
thép không gỉ
Austenitic grades for general, chloride, high-temperature, stabilized, and severe corrosive service.
Duplex Stainless Steel
Duplex stainless steels use a mixed austenitic-ferritic microstructure to combine elevated strength with useful corrosion resistance. Their performance depends on composition, solution heat treatment, fabrication control, and preservation of the intended phase balance.
Hợp kim niken
Nickel alloys are selected when a process environment exceeds the practical corrosion or temperature capability of common steels. Alloy chemistry, product form, heat treatment, fabrication, and the exact media all matter; trade names alone are not a complete specification.
Thép hợp kim
ASTM A182 alloy-steel grades use different chromium-molybdenum systems to support high-temperature pressure service. Their suitability depends on allowable stress, oxidation and corrosion conditions, welding procedure, heat treatment, wall thickness, and long-term operating regime.
Thép cacbon
Carbon steel is the baseline material route for many industrial pressure systems, but “carbon steel” alone is not a procurement specification. Product form, service temperature, notch toughness, heat treatment, dimensional standard, and corrosion allowance must be stated.
Titan
Titanium combines low density with a protective oxide film that performs well in many oxidizing and chloride-bearing environments. It is not universally corrosion-proof: reducing acids, crevices, galvanic couples, temperature, and contamination during fabrication require review.
đồng niken
Copper-nickel alloys are widely evaluated for seawater and marine service because of their characteristic corrosion and biofouling behavior. Performance depends on alloy, flow velocity, water chemistry, commissioning, deposits, galvanic coupling, and fabrication quality.
17-4 PH Stainless Steel
17-4 PH is a precipitation-hardening stainless steel identified as Type 630 or UNS S17400. It can deliver high strength after age hardening, but properties and corrosion behavior depend strongly on the supplied heat-treatment condition.
AL-6XN
AL-6XN is a highly alloyed super-austenitic stainless material identified by UNS N08367. Its nickel, molybdenum, chromium, and nitrogen balance is used to support strength and localized-corrosion resistance in demanding process environments.
Search architecture
Focused enough for search. Clean enough to maintain.
Material pages capture grade and procurement intent. Product categories remain the authoritative catalog structure for flanges, fittings, and valves.
- 01Material family page
Explains grades, tiêu chuẩn, service risks, and selection questions.
- 02Existing product categories
Mặt bích, pipe fittings, and valves retain their current taxonomy and authority.
- 03Grade-aware catalog links
Buyers reach relevant products without new thin combination archives.
- 04GEO-ready answers
Direct FAQs, UNS and ASTM entities, and structured item lists support answer retrieval.
